I am a member of a large non cycling web group and in their open forum area there have been discussions of bicycling and bicyclists. I have been surprised by the number of motor vehicle drivers who do NOT like us, some vehemently so.
The big complaint seems to be the number of bicyclists who routinely ignore traffic laws.
In Nevada the basic bicycle traffic rule is as follows:
NRS 484.503 Traffic laws apply to person riding bicycle.
Every person riding a bicycle upon a roadway has all of the rights and is subject to all of the duties applicable to the driver of a vehicle except as otherwise provided in NRS 484.504 to 484.513, inclusive, and except as to those provisions of this chapter which by their nature can have no application.
There are other provisions covering lighting for night use etc. but basically a bicycle is supposed to obey the same traffic rules as any motor vehicle. Many bicyclists do not. I routinely see fellow bicyclists riding on the wrong side of the road, on sidewalks, against traffic on one way streets, running red lights and other violations of traffic laws. Many are adults who should be aware of the rules they are supposed to follow.
Are some bicyclists our own worst enemies as far as making motor vehicle drivers dislike us? I believe that this may well be the case.
